Every library is an arsenal.

The intelligent and good man holds in his affections the good and true of every land -- the boundaries of countries are not the limitations of his sympathies. Caring nothing for race, or color, he loves those who speak other languages and worship other gods. Between him and those who suffer, there is no impassable gulf. He salutes the world, and extends the hand of friendship to the human race. He does not bow before a provincial and patriotic god -- one who protects his tribe or nation, and abhors the rest of mankind.

Happiness is not a reward - it is a consequence. Suffering is not a punishment - it is a result.
